TOOL FOR HOLDING GLASSWARE WHILE FINISHING.

SPECIFICATION forming part of Letters Patent No. 241,976, dated May 24,1881,

Application filed April 5, 1881. (N0 model.)

To all whom it may concern Be it known that I, ROBERT D. HAINES, ofCorning, in the county of Steuben and State of New York, have inventedcertain new and useful Improvements in a Tool for Holding GlasswarewhileFinishing; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

The object of this invention is to provide a simple and readilyadjustable instrument for holding hollow glassware during the processesof finishing the same; and the invention consists in the constructionand arrangement of parts, as hereinafter more fully described andclaimed.

In the annexed drawings, which fully illustrate the invention, Figure 1is a view of the implement, partly in section, showing the manner ofapplying it to a lamp-chimney. Fig. 2 is a top-plan view; and Fig. 3 isa verticalele vation, showing the position of the adjustable arms beforeintroducing them within a hollow cylindrical body.

A represents a tube, which is enlarged at its lower end to form achamber, A. The upper end of this tube is screw-threaded at a, andsupports a disk or plate, B, that is adjustable upon the threads at bymeans of its collar 12.

Within the tube A is a stem, 0, which is somewhat longer than the tube,so as to project at each end. The lower end of the stem 0 is providedwith a handle, 0. A spring, 0, is coiled around the stem 0 and restswithin the chamber A, so that one end bears against a shoulder, a, atthe upper end of the chamber, and the other end bears against ashoulder, 0, on the stem.

To the upper screw-threaded portion of the tube A, above the disk B andbearing against the same, is attached a nut orcollar, D, which isprovided with lugs d d, preferably arranged in three pairs around thecollar. Between these lugs are pivoted the jointed arms E E,

which are each formed in two sections, the upper sections being pivotedto lugsf f on a collar, F, that is attached to the upper screwthreadedend, b, of the stem 0.

The arms E E are each jointed at e in such a manner that pressure uponthe end of the handle 0, by forcing the stem 0 upward through the tubeA, will bring the arms into a nearly straight or vertical position, asshown in Fig. 3, so .that the implement can be readily introduced into asmall opening. As soon as the pressure upon the handle is relieved thetension of the spring 0, bearing against the shoulder c, forces the stemdownward and throws the jointed arms E into the position shown in Figs.1 and 2, so that they will bear against the interior of the vessel orcylinder into which they may have been introduced. By turning the handle0 the threaded end 12 ot' the stem 0, engaging with the threadedinterior ot' the collar F, will vary the tension of the arms E, so thatthey may be made to bear with greater or less force upon the object, andso hold it with the requisite degree of firmness.

It will be observed that the plate B and collar D are adjustable uponthe tube A, so as to form a firm support for the object.

The implement is constructed of any suitable metal, the arms E being ofany desired size or form to adapt them to the shape of the article to beheld, and are readily adjustable to different sizes.

By the use of this implement the workman can observe the entire outlineof the article he is at work upon, owing to the devices being attachedwithin the glass, which also protects them to some extent from theinjurious efl'ects of heat.

The various parts of the implement are detachable, and may be readilyreplaced when necessary.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In animplement for holding glass articles while being finished, thecombination of a tube provided with a supporting-plate, aspring-actuated stem, and adjustable jointed arms pivoted t0 collars onthe stem and tube in such a In testimony that I claim the foregoing asmanner as to bear against the interior of the my own I have heretoafiixed my signature in object and hold the same firmly, substantiallypresence of two witnesses.
